GMG Signs Halliday for SprintX: RACER.com

The California-based New Zealander, whose resume also includes Champ Car and V8 Supercars, will share a GMG Porsche 911 GT3 R at three rounds with team owner James Sofronas. Porsche factory ace Laurens Vanthoor will contest the other two SprintX rounds with GMG’s co-founder.

“Having Matt join us for the rest of the SprintX season is a major boost to our effort,” Sofronas said. “Matt has become an integral part of our team over the years, and when you combine his speed with experience he is a major asset to both the team and the series. Between Laurens and now Matt I’ll have an impressive couple of co-drivers, and looking at the rest of the talent in the SprintX championship this should be an excellent series of races. We’re excited to have Matt on board, and look forward to the next steps.”
